我已经创建了一个列表
a = [[3, 4], [5], [6, 7, 8]]
我想从此列表中删除 3 个。这是什么命令？
请您参考如下方法:
很多可能的方法
>>> mylist = [[3,4],[5],[6,7,8]]
>>> mylist[0] = [4]
>>> mylist
[[4], [5], [6, 7, 8]]
>>> mylist = [[3,4],[5],[6,7,8]]
>>> del mylist[0][0]
>>> mylist
[[4], [5], [6, 7, 8]]
>>> mylist = [[3,4],[5],[6,7,8]]
>>> mylist[0].remove(3)
>>> mylist
[[4], [5], [6, 7, 8]]
选择你的:)
